2; n liter-:55: that l .lHEtN lCxnHt'. a i izen of th l mit d tates. residing at (Tainan-t iu the county of lloughlou. State of .vlicliiaa. have i\l\!ltlt'\l t-eitain new and u eful In uroxcments in Dumping-(n51 and l do lz l'c fv declare the t'ollmvi.'i; to be a fulhi clear. and exact description f the invention, i

:s will enable others skilled in the art it which it appcrtains to make and use the same. i

'lhis'iuvcniiou rclates to cars and ha special reference to a dumpiu; ar provid d I w th side opening door Une object of the invention is to provide an improred mnstruction of dumping car wherein the body of the car may have a fiat floor. iltl body being arranged to tilt laterally so as to incline the tiooi.

Another object of the invention is to provide a car (it thi haracter with-means whereby the edge oi the body may lie pro jccted beyond the frame of the car a considerable distaucewvlwu in lumping position so that thrmaterial contained in the car may be deposited beyond the. ends of the tie of a railroad track on whi h said car is moving.

A third object of the invention is to provide a novel means of healing the car body lcvel on the frame. A fourth object of the invention is to provide a novel means of locking the doors of a-car of this class. the means being either manually relea able for dumpin; the car when leveh or automatically releasable for l dumping the car when tilted.

A fifth object otthe invention is to provide improved means for locking the releasing means agaimt accidental release.

'ith the above and other objects in view the invention consists of-a wheel supported t'rame whez'con is mounted a car body or box adapted to be tilted to either side of the frame, together with improved locking means for the body and for lateral doors hinged thereto.

The invention further consists in certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the aceoinpanving drawings, and specifically set forth in the claims.

In the form of the device here shown the car is supported on spaced trucks 2) provided with the usual car wheels 21 arranged to run upon rails of the ordinary character. (arried on these trucks is a car frame 22 and this car frame is provided with transverse members 23 when-on are carried filler blocks 24. These filler blocks are shorter than themembers 23 and are positioned in the center of said members so that the ends of the filler blocks lie in spaced relation to the nds of the transverse members 2?. In the angles formed between the filler blocks 2% and the members 23 are brackets 25 each of which is provided with a flange portion 26 arranged t rest on top of and each attached to' the respective end of the filler blocks 24. These brackets are. further provided with a portion 27 arranged to bear against the face of said end and a base 28 which rests on the transverse member or sill 2 3. I'Ixteudin; upward and inward at an acute angle to the base 28 the brackets are provided with a faccmeniberlfl. (arricd on these. l'ai'e members and secured thereto by l l l l means of rivets or bolts are rails which consi t of anticlinally arranged portions 31. downwardly curved at their lower ends as indicated at 32. and the treads of these rails are upwardly curved at the apex and unite Fixedly mounted on the presser bar 53 is a plate 54 and similarly mounted on the press-er bar 51 1s a plate .35. Between these to form a cusp These rails are braced at I then apex by means of a suitable bracing j plate 34.

The frame of the car body proper includes a pair of longitudinal side sills which are I t the doors are free to move, these springs United adjacent each end by spaced cross;

sills 3H. Extending upward from the proxiniatc or central cros sills 36 are posts 37.

Supported on the inncr faces of these posts.

arc car ends 3S. spaced that they embrace the rails Ill. one of the liit'liibcrs of each pair lying adjacent said rails toward the center of the car and These members 36 are so 1 v but one of the doors swings open, the

the other member lying adjacent the rails g toward the end of the car.

Supported in those members ll; are hort shafts It!) whcrcf on are rotatablv mounted rollers or wheels 40 each of which i provided with a peripheral groove 41 so arranged as to form a:

flange l2 on each side of the wheel. These whccls rest on the treads of the rails ill and lhc diameters of the wheels at the bottom of the grooves 41 are equal to the diameters of the circle which form the sides of the cusps 33. Furthermore. the short shafts 39 are spaced apart at such a distance that when one of the wheels to bears against one ide f a cusp 233 the other wheel 40 will occupy the position shown in Fig. T. that is to say. at approximately the lower end of the rail 31 opposite the side of the cusp against which the first mentioned \vhccl bears;

lil'hl'tOIl the car ends 38 the car is providcd with the ordinary car floor 43. Extending across the car innnediately over the members 343 at each end of the car are transverse top nicmlwrs 44 and closing in the space between the members 36 are side lllt'lli' licrs or car sides 45. 'lhcsc car sides do not extend inward beyond thc car ends 38 but terminate thercagainst. Carried in the members 1 1 at opposite ends thereof are pivot bolts 46 whet-con arc rotatably mounted hinge members 47 which are. formed with I split portions extending over the car sides as it icated in Figs. 10 and ll at 48. Secured to these split portions are side doors 4t), the doors being thus hinged at the upper cdgc. and. it not secured. free to swing at the lower edge. 'llicso hinge members extend downward at the inncr ends and are provided with pivot pins 50. Between the inner ends of the hinge members extends a double compression spring nicmbcr. This member comprises a prcsscr bar 51 having its outer end held by the pivot pin 50 and having its inner end forked as at 52. To

the. ther pivot pin 54) at cach end of the car f is secured a prcsscr bar 52 and this prcsser bar lies between the sides of the fork 52.

will expand and raise the door to the position shcwn m dotted lines In Fig. 6, the

' spring ltrclf and the presser bars connected therewi'li assuming the position shown in l 'ig. i'. t is to be understood that but one side of the car is unlocked at a. time so that amount of extension of the spring bein merely enough to insure full opening 0? one door.

In order to retain the tilting body in its level position suitable locking nieans are provided. Each of these locking means comprises a chain 58 preferably located at each corner of the car and each of these chains is preferably connected to the lower end of one of the rails 31 as indicated at 55 b'ueul'cd to the car body immediately above each of the chains 5b is a hook comprising a body portion 00 which is provided with a loop at its: upper end for attachment to an eye nolt tll lixedly secured to the car body. This loop 60 consists of a single length of stilt wire or bar rcbent upon itself and the lower ends diverge as at- (32. From these diverging ends the extremities of the bar are bent forward and around to form spaced eyes (33 wherein is held a pin 64. Upon the pin (it is mounted a retaining hook comprising a single length of wire or bar bent around the pin to form an eye (35 and provided with an inner upstanding terminal (it; and an outer upstanding terminal oi. the latter being substantially twice as l ng as the inner terminal. Slidable on the body of the book 60 is a keeper ring 68 which is engagcable over the end of the terminal 67 when the device is locked. The chain 58 terminates in a ring (it) adapted to receive the terminal (37 so that this ring is held between the two terminals 66 and 67, and when locked. the ring 68 prevents the disengagement of the ring tit) from the terminal (37. When, however, the rin 68 is raised the terminal (37 is free to revolve and thc revolution of this terminal carries with it the terminal (36 and thus forces the ring til) out, of engagement with the hook 60. It will now be plain that if the hooks upon one side of the car he released the car may move freely toward the other side, the amount of movement being limited by the wheels 40 on the released side engaging a'gainst the cusps 33.

- In order to provide for holding the doors in locked position the sides 49 are equipped with suitable braces eaeh of which has a lower end 71 which is hent inward beneath the sides of the ear and terminates in an extremity- 7'2 provided with ears 73 on the 0pposite ides thereof. The longitudinal members 35 of the cztr are provided with (lips 74 each of which has :1 pair of spaced and perforated ears 75 adapted to receive a pivot pin T6.
